Some structures are not saturated with binder, so first-stage removal is skipped...
Abstract
Binder removal approaches involve various combinations of heat, solvents, vacuum, and pressure. In each variant, the goal is binder removal without component damage. This chapter addresses the factors that control success, showing how process decisions depend on the powder and binder characteristics. The chapter starts with a comparison of binder-, lubricant-, and polymer-removal situations that arise after powder shaping and then describes the general principles of binder removal in powder-binder techniques. The subsequent sections discuss in detail characteristics, operating procedure, equipment setup, advantages, limitations, and applications of first- and second-stage binder removal processes, as well as the factors influencing these processes. Cost issues associated with binder-removal technologies are also discussed.

Abstract
Generally, binders consist of at least three ingredients: a backbone to provide strength (compounds such as polyethylene, polypropylene, ethylene vinyl acetate, and polystyrene); a filler, such as polyacetal and paraffin wax, to occupy space between particles; and additives, such as stearates, stearic acid, or magnesium stearate, as well as phosphates and sulfonates, to adjust viscosity, lubricate tooling, disperse particles, or induce binder wetting of the powder. In the case of binders deposited via ink jet printing, the binder contains solvents to lower the viscosity for easier jetting. The chapter provides a detailed description of these constituents. The requirements of a binder as well as the factors determining the physical and thermal properties of polymers are discussed. Then, two factors associated with solvation of polymers, namely solubility parameter and wetting, are covered. The chapter ends with information on the specification of polymers used in binders.

Abstract
This article addresses some established protocols in characterizing thermoplastics, whether they are homogeneous resins, alloyed or blended compositions, or highly modified thermoplastic composites. It begins with a description of various approaches used for the determination of molecular weight (MW) by viscosity measurements. This is followed by a discussion of the use of cone and plate and parallel plate geometries in determining the viscoelastic properties of a polymer melt. Details on some of the chromatographic techniques that allow determination of MW and MW distribution of polymers are then provided. The article concludes with information on three distinctive, but complementary operations of thermoanalytical techniques, namely differential scanning calorimetry, thermogravimetric analysis, and thermomechanical testing.
